You run a new transport company with a 1825-day mandate. Build whatever network you like (road, rail, air, water). When the mandate ends, your company keeps running **without you** for 365 more days; the reward is your **net worth (cash minus loan) after that run-off**, on a log scale: do... | 1,825 | 365 | {"max_forks": 2, "max_fork_days": 365} | {"w_idle": -25800, "w_base": 11940, "score": "log50"} | {"gen_version": 1, "split": "dev", "landscape": "temperate", "map_log2": 8, "starting_year": 1990, "settings": {"difficulty": {"number_towns": "2", "industry_density": "4", "terrain_type": "1", "quantity_sea_lakes": "2", "max_loan": "300000", "initial_interest": "4", "vehicle_breakdowns": "0", "construction_cost": "0",... | 0 | 0.176291 | [

Railhead
Railhead is a reinforcement learning (RL) environment. In Railhead, a language model plays the transport game OpenTTD directly. The model controls one company with the same commands that a human player uses. This dataset contains the Railhead tasks, the oracle trajectories, and the games of the models in the arenas. The documents of Railhead follow ASD-STE100 Simplified Technical English.

Config tasks
Each row is one task. The important columns are:
| Column | Description |
|---|---|
task_id |
The identifier of the task. It is the same in Harbor and in the image. |
family, split |
The task family and the split (train, dev, or ood). |
instruction |
The text that the agent receives. |
objective, scenario, limits |
The task specification (JSON). |
idle_reward, oracle_reward |
The certificates: the reward for no play and for the oracle. |
start_sav |
The sealed start state (an OpenTTD savegame). |
task_binary |
The complete Harbor task directory (tar.gz), with the tests and the oracle solution. |
Config trajectories
Each row is one trajectory.
The policy column is oracle for the scripted oracle.
For a game of a model in an arena, the policy column is the name of the model (for example claude-opus-5-5 or gpt-6-astra).
These games are in the dev split, for the tasks arena-dev-0005 and arena-dev-0100.
The actions_jsonl column is the action log.
The verifier replays this log from start_sav and calculates the reward.
The components column contains the reward and the diagnostic values.
The turn_credit column contains the leave-one-turn-out credit for each turn.
Task families
| Family | Objective | Reward |
|---|---|---|
deliver |
Deliver a quantity of a cargo to one industry in 300 days. | min(1, D / Q) |
deliver_bid |
The deliver objective with a promise of a quantity. |
A proper newsvendor score, linear in 0 to 1 |
impossible |
A contract that no company can complete. | 1 if the agent abstains, else 0 |
simops |
Repair a truck route that has faults. | Run-off deliveries between the broken and the repaired network |
tycoon |
Open play for 365 days. | Net worth after a 730-day run-off, 0.5 at the scripted baseline |
The ood split uses the arctic and tropic climates.
The cargo chains of these climates are not in the train split.
Use the tasks
- Pull the image:
docker pull ghcr.io/rachittshah/railhead:0.1.0. - Extract
task_binaryof a row to a directory. - Run the task with Harbor:
harbor run -p <task_dir> -a <agent> -m <model>.
The reward is in verifier/reward.json.
The verifier replays the action log of the agent from the sealed start state.
A change to the live game that is not in the action log has no effect on the reward.
License
The dataset and the Railhead code have the MIT license. The environment image contains OpenTTD, which has the GPL-2.0 license.
